SPECIFICATION forming part of Letters Patent No. 747,502, dated December 22, 1903. Application filed May 23,1902. stain N... 108,697. (No model.)

To all whom it may concern:

Be it known that I, HENRY SYMONDS, acitizen of the United States, residing at Long beach, in the county of Los Angeles and State of California,-have invented a new and useful Acetylene-Generator, of which the following is a specification.

This invention relates to apparatus for generating acetylene gas; and some of the objects of the invention are to produce an apparatus of this character which will be simple and cheap in construction and at the same time positive and effective in operation.

Another object of this invention is to provide for the production of the acetylene gas in a cool or comparatively cool state or condition.

I It is also an object of this invention to pro vide an apparatus wherein the carbid cartridge or receptacle is readily removable and accessible and to provide a water seal for said cartridge or receptacle.

Furthermore, it is an object of this invention to produce a carbid cartridge or recep tacle so constructed as to prevent the entire weight of the carbid from resting upon the valve and to so construct the valve and valveseat that particles of carbid becoming caught therebetween will be forced into the receptacle.

Vith these and other objects in view the invention consists,essentially, in the construction, combination, and arrangement of parts, substantially as more fully described in the following specification. and illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is an elevational view, partly broken away and partly in section. Fig. 2 is a perspective view of the apparatus on a reduced scale. Fig. 3 is a longitudinal central sectional view of the apparatus, minor parts being shown in elevation; and Fig. 4 is an enlarged detail view, partly broken away, of the carbid cartridge or receptacle.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, the reference character 1 designates cylindrical casing closed at one end, as at 2, and provided with lateral hollow extension 3, with which communicates a vertical sleeve or guide 4,wherein is mounted an actuating-rod 5, having an angular extremity 6, by means of which the same is operated, and formed on or connected with the other end of said rod is an agitating blade or scraper 7, Figs. 1 and 3 of the drawings, the function whereof is to agitate or scrape up the lime which settles upon the bottom 2 when it is desired to clean out the casing, as will be readily understood.

The casing 1 is preferably provided near the bottom thereof with a connection 8, wherein is mounted avvalve 9, carrying an arm 10,. and it is with this connection 8 that a pipe or tubing is adapted to be connected when it is desired to flush or wash out the casing, and an air-inlet 11 is preferably connected with the casing above the connection 8 and is provided with a valve 12, carrying an arm 13, constructed to so operate with the arm 10 of the valve 9 so that the latter valve cannot be opened until the arm 13 is raised and the valve 12 opened, thereby admitting 7 air into the casing.

The water for flushing the casing is admitted through a vertical pipe 14, Fig. 3, preferably terminating in a funnel 15,-and the water and impurities are drawn off through the connection 8, as before stated, and the easin g is preferably provided with a diaphragm or false bottom 16, Figs. 1 and 3, and with a spout 17, by means of which water is int-roduced into the upper portion of the casing above the diaphragm 16, and it will be understood that water is introduced into the lower portion of the casing below the diaphragm 16 through the vertical pipe 14 to act on the carbid, as will be readily understood.

The casing l is preferably provided with brackets 18 to receive and support guide-rods 4 19, against which operate guides 20, formed on or connected with the dome or cover 21 to regulate themovement thereof during the 5 operation of the apparatus, as hereinafter more fully explained,

Formed on or connected'with the casing 1 is a drying chamber or receptacle 22, Fig. 3, having connection 23 with condensing-cham- I00 ber 24:, and the connection 23 is preferably with a valve 25 and with a pipe 26,

provided communicating with the vertical outlet-pipe 27 within the casing above the diaphragm 16, and the drying-chamber is preferably provided with an outlet 28, with which is connected the pipe communicating with the service-pipes, and within the drying-chamber 22 is preferably deposited alternate layers of excelsior and cotton or similar material.

Connected with one side of the casing 1 and passing therethrough is an excess-gas-escape pipe 29, which preferably extends from above the diaphragm to the top of the casing within the same, Fig. 1 of the drawings, and formed on or connected with the diaphragm l6,v

around the central opening 30 therein, is a stand-pipe 31, preferably terminating in the same plane with the open end of the casing 1, and connected with the diaphragm 16 is a vertical pipe 32, preferably of the same height of the stand-pipe 31 and provided with a removable cover 33, Fig. 1, which is elevated by the accumulation of the gas in the vertical pipe 32, which elevates the cover 33 and permits the gas to pass between the same and the vertical pipe 32 out under the edge of the cover, as indicated by an arrow in Fig. l of the drawings, and it will be understood that water is introduced into the casing 1 above the diaphragm 16 until the same stands sub stantially on a level with the openings therein communicating with the spout 17, Fig. 1, so that the gas passing out from under the cover 33 will also pass upwardly through the water, and be cooled thereby, into the upper portion of the dome 21, thence down through the outlet-pipe 27, through the connection 26,into the drier 22, and out to the servicepipes.

Formed on orconnected with thedome21isa cylindrical closure 34, provided with a lateral outlet 35, and the closure is constructed to inclose or cover the upperend of the exhaustpipe 29, so that when a superabundance of gas accumulates in the dome and raises the latter until the outlet 35 in the closure 34 is elevated above the water-level in the casing 1 the gas will enter the closure through said out-let and pass thence into the exhaust or escape pipe 29 to the open air, Figs. 1 and 3, thereby relieving the excessive accumulation of gas in the dome 21, as will be readily understood.

Mounted within the central opening in the top 36 of the dome 21 is a cylinder 37, the upper end of which cylinder is supported by a frusto-couical brace 38, Fig. 3, and within the cylinder 37 is an interior cylinder 39, connected with the exterior cylinder 37 by an annular ring or band 40, substantially as illustrated, and water is introduced between the interior and exterior cylinders 39 and 37, respectively, until the annular chamber 41, formed thereby, is substantially filled,whereupon the cover or closure 42 is introduced into the annular chamber 41 until the top 43 of the closure rests upon the rim of the interior cylinder 39, substantially as illustrated in Fig. 3 of the drawings, and the closure 42 is rotated until the locking-bar 44 upon the top 43 engages the fastening devices 45 upon the exterior cylinder 37 and prevents the accidental disengagement of the closure 42 during the operation of the apparatus.

Referring now particularly to Figs. 3 and 4 of the drawings, there is illustrated an improved cartridge or carbid receptacle 46,preferably cylindrical in form and provided with a closed end having an annular rim or flange 47 constructed to rest upon the end of the stand-pipe 31,'Fig. 3, to support the cartridge in operative position within the apparatus, and the other end of the cartridge or receptacle is preferably contracted or pointed, substantially as shown at 48, and around the end 48 is secured a frusto-conical ring 49, constructed to receive and discharge the condensation oceuring during the operation of the apparatus and prevent the same from entering the end of the cartridge around the valve 50, as will be readily understood.

Depending from the top of the cartridge or receptacle is a sleeve 51, provided at the free end thereof with a double inclined portion 52, adapted to receive the pressure of the superimposed carbid, and thereby relieve some of the pressure upon the valve 50 to facilitate the operation of the valve. The valve 50 is provided with a stem 53, passing through the depending sleeve 51 and carrying a crosshead 54, connected by chains 55 with the interior cylinder 39, allowing a limited amount of free relative movement between the cylinder and the carbid-receptacle, and a spring 56 may be mounted upon the stem 53 between the cross-head 54 and the top of the cartridge to normally seat the valve 50. By means of this construction of the cartridge or carbid-receptacle the pressure of the carbid is largely removed from the valve and the efliciency of the same is greatly increased thereby, and particles of carbid caught between the valve and the valve-seat will be forced into the cartridge or receptacle by the construction of the valve-seat and valve and by the action of the spring operating the latter. Furthermore, the contents of the cartridge or receptacle will not become injured by the condensation or moisture entering around the valve during the operation of the apparatus.

The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following explanation thereof.

When it is desired to start the operation of the apparatus, water is introduced into the lower portion of the casing through the pipe 14 until the water stands at the proper level. Then water is introduced into the upper portion of the casing by means of the spout 17 and the annular chamber 41 is substantially filled with water, whereupon the dome is socured in position, and the cover 42 is introduced into the annular chamber 41 after the carbid cartridge orreceptacle shall have been first filled with carbid and introduced into the stand-pipe 31. With the parts in this position it will be understood that the upper'part of the dome is filled with air, which is drawn off through the outlet-pipe 27 and the drier 22 by opening the valve 25, whereupon the dome descends until the top 43 of the cover 42 rests upon and depresses the valve-stem 53, thereby opening the valve 50 and discharging the carbid into the water in the lower portion of the casing, whereupon gas is generated, which passes up through the pipe 32, Fig. 1, down under the closure or cover 33, and up through the water in the upper portion of the casing, thereby cooling the gas in its passage to the upper portion to the dome, from whence it passes down through the outlet-pipe 37 and connection 26 into the drier 22, where it is dried by passing through the excelsior and cotton therein, and the dried gas finally passes out through the pipe 28 to the service-pipe.

It is not desired to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, for it is obvious that the carbid-receptacle is capable of use with apparatus of slightly different construction. Therefore the right is reserved to make all such changes in and modifications of the said construction as come within the spirit and. scope of the invention.
